REGULATING DEVICE FOR PETROLEUM-MOTORS.

SPECIFICATION forming part of Letters Patent No. 780,705, dated January21, 1905.

Application filed March 22, 1902. Serial No. 99,500.

To all whom it mar concern:

Be it known that we, FERDINAND OHARRON and LnoNoE GIRARDOT, citizens ofthe Republic of France, residing at No. 45 Avenue de la Grande Arme.Paris, in the Republic of France, have invented certain new and usefulImprovements in Regulating Devices for Pevide mechanism whereby theescape-valves of such motor may automatically be opened after eachexplosion when the motor is running at normal speed.

The invention also has for its object to add devices to the saidmechanism, so that when the motion of the said motor exceeds normalspeed the said escape-valves may be closed and the said motion reducedto normal'speed.

The invention has also divers other objects, which will be more fullyhereinafter set forth.

The nature .of the invention consists in the combination ofreciprocating sliding rods partly actuated by springs, with othermechanism,also partly actuating said rods,whereby the said escape-valvesmay be-opened as required.

The nature of the invention also consists in the combination, withsliding rods carrying friction-rollers, of means whereby such rods aremoved to open said valves as required.

The nature of the invention also consists in the combination, withsliding rods carrying friction-rollers. of revolving cams engaging saidrollers. and thereby actuating said rods to open said valves asrequired.

The nature of the invention also consists in the combination, withsliding rods carrying friction-rollers and partly actuated by springs,of revolving cams engaging said rollers, and thereby also partlyactuating said rods to open said valves as required, a revoluble shaftwhereon said cams are mounted, and means whereby said cams are moved onsaid shaft so as to disengage them from said rollers and allow the saidvalves to remain closed as re- Fig. 2 is a side view of the two to oneway shaft with its cam-sleeve and earns. Fig. 8 is an end View of oneside of our invention. Fig. 4 is a sectional view taken on the linepassing through the cam cl of Fig. 2. Fig. 5 is a view showing thedevice in connection with the escape-valves and the speed regulator.

.In the said drawings, a designates the two toone way shaft. This isjournaled in bearings b, which are supported by the frame of the motorto which the device is attached. The middle portion of this shaftbetween said bearings is square. Upon this square portion is mounted thesleeve 0, which is not of sufiicient length to extend through the entiredistance between the bearings 6. This sleeve and the shaft areillustrated in section in Fig. 4. This sleeve is so arranged that whileit is carried in rotation by the shaft a it is also capable of beingslipped endwise thereon. To insure the easy shifting and true guiding ofthe sleeve and also to reduce the friction to a minimum, the two rings 1and 2 are fastened one in eachend of the sleeve. These have squarecentral openings adapted to fit on the said square partof the shaft 60.Y

()n the exterior of the sleeve 0, one at each end, are the cams d and f,integral with the sleeve and arranged so thattheir longer axes will beat right angles to each other. In the middle portion of said sleeve aretwo annular collars 3 and 4, between which there is an annular recess 5.

Parallel to the shaft a is a rod g, free to slide endwise in bosses castintegral with the bearings b. This rod carries a fork h, which engagesthe sleeve, 0 in the annular recess 5. It also carries at one end anadjustablefork e', which engages the annular recess of the sleeve of acentrifugal-force regulator. This regulator is shown in the drawings;but it' may be of any available construction, so that it has anadaptable sleeve engaging the end of the shaft a. The forke' is securedin place with nuts, as illustrated. 1

p and q designate vertical bearings which are to rest on proper supportsin the frame of the machine. In these guides slide the rods m and a. Thesprings r partly actuate these rods. These rods also carry at theirlower ends the friction-rollers 7c and Z, which engage the cams d and f.These rods m and n are located directly under the stems of theescapevalves of the motor, so as to engage them, as hereinafter setforth.

It will now be seen that as long as the motor maintains its normal rateof speed the cams d and f alternately raising the rods are and a willcause them to alternately engage the stems of the escape-valves of themotor, and thereby alternately openthe valves, each one in proper timefor the escape of the products of explosion; but if the motor shouldattain too great speed the sleeve j of the regulator will be movedendwise on the shaft a, and, carrying With it the fork 2', the rod 9,and

the fork h, will also cause the sleeve 0 to "slip endwise on the shafta.

This Will move the cams d andf out of engagement with the rollers 70 andl. The rods m and n will then cease to move, and the escape-valves ofthe motor will remain closed until the motion of the motor decreases tonormal speed. Then the parts of the mechanism returning to theirnormal'position the machine will perform its normal functions at itsnormal speed.

We do not, however, confine ourselves strictly to the construction andarrangement herein set forth, for it is evident that under the scope andspirit of our invention we may make divers slight variations withoutdeparting therefrom.

Having now fully described what our invention is and how it isconstructed and used, what we claim, and desire to secure by LettersPatent, is

In a regulator for petroleum-motors, the combination with the slidingvalve-actuating rods, guides therefor, and friction-rollers carried bythe rods, of a shaft, a sleeve slidably mounted thereon, having a cam oneach end thereof, said cams engaging with the rods, rings on saidsleeve, a rod 7 arranged parallel to said shaft, a fork integral withsaid rod and engaging with the sleeve between the rings thereon, asecond sleevej slidahl y n1ouuted on the shaft, a centrifugal governorfor moving said sleeve and a second fork adjustably secured to the rod 1and connected to the sleeve whereby on the movement of the sleeve j thecams will be disengaged from the friction-rollers on the rods.

In witness whereof we have hereunto set our hands in presence of twowitnesses.
